Was this before or after Paul was supposed to have died and was replaced by Billy Shears? LOL!!
It does make you think. They never toured live after 65 / 66 except for the rooftop gig.
They reckon that they had to cover it up because the govt at the time didn't want Macca to be grieved for as a national hero when Churchill had only just died and they didn't want that event to be overshadowed.
But ... any theory can fit if you let it ...
